Hi Anastasia,

Yes, launching the same command line from terminal produced the same error, but at the same time we realized we were using the wrong magnetic/phase dicoms.....which weren't magnetic/phase images at all.
Could that be the cause of the failure? I would answer the question myself but right now I don't have the correct images to test it.

Best,
Elia.

Subject: Re: [Freesurfer] Tracula preprocessing error ( set dob0 = 1 )

 
Hi Elia - It looks like this file didn't get created:
/home/elia/scripts/Tracula/LCL/Tracula-B0-Input_zip/T13D/timePoint1/dmri/dwi.nii.gz
 
The command that was supposed to create it was epidewarp.fsl. You can find 
the command line that begins with "epidewarp.fsl" in the log file that you 
sent me. When you run that whole line directly from the unix command line, 
do you get any errors?
 
a.y
